Battle of the Titans is a 5-reel slot machine with up to 20 win lines, where the player can play between 1 and 20 lines, and a free spin feature using a Clash of the Titans theme. The reel symbols used are 10 J Q K A for lower wins and graphics of Zeus, Perseus and Andromeda as the bigger win value symbols. Bubo, the clockwork owl is used as a wild symbol and is animated when used in a winning combination. The wild symbol replaces all symbols except the scatter trigger.

The free spins feature is triggered by 3 or more scatter symbols appearing in the reel window. These will be a graphic of Medusa. Free spins are awarded dependant on the number of scatter symbols present. A win amount is also given as it is possible for the free spin feature to not give a win during the feature. Scatter symbols can only appear one per reel so a maximum of 5 can be displayed

When in the free spin feature the awards are the same as in the main game. Also, when a wild lands in view it is frozen in place for the duration of the free spin feature (sticky wilds). The indication of these wilds being frozen in place while the free spin game is active is done by medusa appearing from the right hand side, a beam coming from her eyes towards the titan warrior who then deflects it with his shield towards the wild symbols that needs freezing in place. If there is more than one new wild appearing on a spin then the sequence is repeated until all the new wilds are changed to the stone version of the wild symbol. It is also possible to add to your number of free spins if the scatter symbols reappear in the reel window whilst playing the free spin feature. The feature can be retriggered unlimited times.
